Data consistency in distributed system

In this post, we give a short tutorial on consistency levels - explaining what they do, and how they work. Much of the existing literature and online discussion of consistency levels are done in the context of multi-processor or distributed systems that operate on a single data item at a time, without the concept of a “transaction”. In this post we give some direction for how to think about consistency levels in the context of ACID-compliant database systems.
